Door body

ABSTRACT

A door body has a stile that is slotted at its front end and receives a core that is relatively stiff; but somewhat resilient. A pad located at opposite sides of said core is yielding and resilient. A compliant sheet covers said pad, and provides an exterior cover for the door body.

Another object is to provide such a door body that is strong enough towithstand said impacts repeatedly for an indefinite length of time, yetis simple in construction and relatively inexpensive to manufacture.

The foregoing and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a construction,combination and arrangement of parts such as is disclosed by thedrawing. The nature of the invention is such as to render it susceptibleto various changes and modifications, and therefore, I am not to belimited to the construction disclosed by the drawing nor to theparticular parts described in the specification; but am entitled to allsuch changes therefrom as fall within the scope of my invention.

In the drawing:

FIG. 1 is a front elevational view of my door body.

FIG. 2 is a sectional view, greatly enlarged, taken on the line 2-2 ofFIG. 1.

FIG. 3 is a sectional view similar to FIG. 2; of a modified form of myinvention, and showing the front extremity of said door body.

As illustrated, my door body has a core of relatively firm sheetmaterial that is somewhat resilient and non bendable when serving aspart of the main body of a door that is regularly opened by forcefulimpact, as when a moving cart or truck strikes it. It may be made of athermo-forming material, or another suitable material, such as anacrylic polyvinyl chloride alloy plastic sheet. It may be one-eighthinch thick, for instance.

At the front and rear of said core 10 is a yielding resilient pad orsheet 14, which commences at a stile 20, later referred to, and extendsat one side of said core 10 to the outer end of the door body and thenreverses and extends inwardly at the opposite side of said core 10 andterminates at the edge of said stile 20. This sheet 14 is shown as aunitary one, and is thicker than said core 10 and preferably is morethan two times as thick. For instance, said sheet 14 may be one-fourthor onehalf inch thick while said core may be one-eighth inch thick. Thissheet or pad 14 is made of yieldable, resilient material such as spongerubber, urethane or neoprene, and is relatively resilient compared tosaid core which is relatively stiff, although said core, as well as saidsheet, will yield upon forcible impact.

A cover sheet or skin 16 of compliant material, such as rubber, extendsaround the door body, including said stile 20, extending to the outerend of said door body, beyond said core 10 and pad 14 to provide aflexible nose 18, as shown in said FIG. 3. Said cover sheet l6 continuesfrom said nose 18 to said stile 20. It is cemented to said stile andpad.

Said door body has a stile or mount 20 at its inner end, which may beformed of wood, plastic or extruded aluminum, for instance, preferablybeing solid and extending the full height of said body. It has a slot 21formed therein extending from top to bottom, and from its outer endinwardly a relatively short distance such as l /zinches. This slot 21receives an inner end portion of said core 10 which is cemented orpinned, or both, to said stile. The cover sheet 16 is covered on theoutside by a cap 22 where it overlaps said stile. Said cap is preferablymade of metal that extends around said stile and a post 32, laterreferred to.

Said stile 20, cover sheet 16 and cap 22 are shown as retained by a bolt24 extending through them, on which a head 26 is formed. Said coversheet 16 and cap 22 are further retained in position by screws 28 and 30that enter said stile 20.

A privot post or pipe 32 extends from top to bottom of said door body atthe inner end thereof, being fastened by a pin 34 extending through saidpost and cap 22 and having a head 36 formed thereon. Said door body maybe provided with a window 40 as shown in said FIG. 1.

In said FIG. 3 I show a modified form of cap 22a, without said post 32,and with said cover sheet 16 extending to the inner end of said doorbody. The latter sheet 16, said stile 20 and said cap 220 are fastenedtogether by screws 42 and 43. A hinge 44 is fastened to the inner end ofsaid cap 22a in any well-known way.

In forming said flexible nose 18 the material of said resilient pad 14is compressed where a tum is made at the point beyond the outer end ofsaid core 10 to the outer end of said cover sheet.

What I claim is:

l. A door body comprising a core extending straight and of relativelyfirm but resilient material, pad means on opposite sides of said door ofcompressible but resilient material, the latter material being moreresilient than said core material, a cover sheet of compliant materialexteriorly of said pad means and core and providing a cover for saiddoor body, a solid stile forming the inner side portion of said doorbody and having a slot extending inwardly from the inner end portion ofsaid body, a portion of said core extending into said slot, said padmeans terminating at said stile, said pad means being unitary andreversing itself beyond the outer end of said core.

2. A door body as in claim 1, the portions of said pad means reversingitself being compressed between the outer end of said core and the innerend of said cover,

said core being non-bendable.

1. A door body comprising a core extending straight and of relativelyfirm but resilient material, pad means on opposite sides of said door ofcompressible but resilient material, the latter material being moreresilient than said core material, a cover sheet of compliant materialexteriorly of said pad means and core and providing a cover for saiddoor body, a solid stile forming the inner side portion of said doorbody and having a slot extending inwardly from the inner end portion ofsaid body, a portion of said core extending into said slot, said padmeans terminating at said stile, said pad means being unitary andreversing itself beyond the outer end of said core.
 2. A door body as inclaim 1, the portions of said pad means reversing itself beingcompressed between the outer end of said core and the inner end of saidcover, said core being non-bendable.
